1. WARNINGS AND PRECAUTIONS FOR SAFETY
Please observe the following safety precautions in order to use safely and correctly the refrigerator and to prevent accident and danger during repair. 1. Be care of an electric shock. Disconnect power cord from wall outlet and wait for more than three minutes before replacing PCB parts. Shut off the power whenever replacing and repairing electric components. 2. When connecting power cord, please wait for more than five minutes after power cord was disconnected from the wall outlet. 3. Please check if the power plug is pressed down by the refrigerator against the wall. If the power plug was damaged, it may cause fire or electric shock. 4. If the wall outlet is over loaded, it may cause fire. Please use its own individual electrical outlet for the refrigerator. 5. Please make sure the outlet is properly earthed, particularly in wet or damp area. 6. Use standard electrical components when replacing them. 7. Make sure the hook is correctly engaged. Remove dust and foreign materials from the housing and connecting parts. 8. Do not fray, damage, machine, heavily bend, pull out or twist the power cord. 9. Please check the evidence of moisture intrusion in the electrical components. Replace the parts or mask it with insulation tapes if moisture intrusion was confirmed. 10. Do not touch the icemaker with hands or tools to confirm the operation of geared motor. 11. Do not let the customers repair, disassemble and reconstruct the refrigerator for them selves. It may cause accident, electric shock, or fire. 12. Do not store flammable materials such as ether, benzene, alcohol, chemicals, gas, or medicine in the refrigerator. 13. Do not put flower vase, cup, cosmetics, chemicals, etc., or container with full of water on the top of the refrigerator. 14. Do not put glass bottles with full of water into the freezer. The contents shall freeze and break the glass bottles. 15. When you scrap the refrigerator, please disconnect the door gasket first and scrap it where children are not accessible.

REMARKS
5. Control way of Error (if any) 1) “F1” error Cause : F-sensor disconnection or short Check point : Measure the resistance between both terminals after separating CN8 (or CN15) of the Main PCB. If F-sensor is disconnected or shorted , change the F-sensor in the freezer compartment. How to reset : If F-sensor is normal, the error is terminal temperature. 2) “R1” error Cause : R-sensor disconnection or short Check point : Measure the resistance between both terminals after separating CN7 (or CN14) of the Main PCB. If R-sensor is disconnected or shorted , change the F-sensor in the refrigerator compartment. How to reset : If R-sensor is normal, the error is terminal temperature. 3) “rt” error Cause : RT-sensor disconnection or short (full down) Check point : Measure the voltage of “A” part on the Main PCB. If the voltage is 0.5V~4.5V, it is normal. If the voltage is 0V (short) or 5V (disconnected), change the RT-sensor on the Main PCB How to reset : If RT-sensor is normal, the error is terminated automatically.
A
4) “d1” error Cause : D-sensor disconnection or short (full down) Check point : Measure the resistance between both terminals after separating CN8 (or CN15) of the Main PCB. If D-sensor is disconnected or shorted , change the D-sensor on the evaporator. How to reset : If D-sensor is normal, the error is terminated automatically. 5) Door error (“dF” “dR” “dH” on display) Cause : in case it senses that door is open for more than 1 hour. Check point : F/R door is opened or not. 6) “C1” error Cause : in case comp. works for over 3 hours when D-sensor temp. is over -5℃ Check point : Refrigerant leakage. 7) “F3” error Cause : in case defrosting return is done by time limit of 80 min Check point : Measure the resistance between both terminals of the defrost heater. (Assembled with evaporator) If the resistance is ∞Ω (disconnected) or 0Ω (short) change the 8) “d2” mode (A/S forced defrosting mode) Push “Refrigerator Set” button 5 times while pushing “Freezer Set” button simultaneously. Control : A/S forced defrosting control (Pre-cool is deleted) If D-sensor temp. is over 13℃, the mode is terminated automatically. Refer to the 4-3. . 18
CONTENTS
REMARKS
9) “EI”ERROR Cause : I-SENSOR disconnection / short Check point : Measure the resistance between both terminals after separating CN11 of the Main PCB. If F-sensor is disconnected or shorted , change the I-sensor in the automatic ice maker. 10) “EF” ERROR Cause : When Flow-sensor ERROR (There is no Pulse during some time) The number of pulse signal is below 10 by 1 sec during water supply. Check point : Water supply line 11) “Eg” ERROR Cause : I-sensor temp (5min after water supply) doesn’t go up. Check the I-sensor or water supply line. 12) “ES” error (Micro switch error) Cause : When it senses 1min continuously Check the Micro switch of the dispenser.
13) “Ea” error Cause : Malfunction of ice drop motor. Check the motor by pushing test switch. 14) “Eu” error Cause : Switch (which senses if the ice is full or not) is in error. Control : When dropping the ice, the motor just rotates 90 degree. Termination : When the switch is in normal.
15)“EA“ ERROR Cause : When sensing Ice dropping by time 3 times in level sensor SW Error. Control : Stop of Ice Maker Termination : With normal level switch. Re-input of power or push if icemaker test switch. 16)“Et” ERROR Cause : Level switch error (No pulse is sensed for some time) Control : By time (Supply mode is skipped) Termination : Normal condition. * When all ERROR CODE is normal, the Refrigerator reset

Remarks ● The fan is sending out cold air to circulate it through the compartments. When the air is touching the surface of louver or liner wall, such sound can make. 54
Troubleshooting of Fan Noise
1. Fixing or Fastening of Fan Motor
1) Check if fan motor frame of the assembly is fastened tightly with screws to the liner wall. Unless it is tight, vibration of shaking can make.
2) Check if fan motor and fan are hanged down. Fan working sound can be louder if they are not set right.
2. Any Touch Sound from Fan
1) Check if sealing sponge on the insulator touches the fan. If so, set it again not to touch it. 2) If any damage on the insulator around the fan rotation is found, set the fan motor assembly right not to touch it.

9-2. Precautions During Heavy Repair Items Use of tools.
Removal of retained refrigerant.
Precautions 1) Use special parts and tools for R-134a or R-600a
1) Remove retained refrigerant more than 5 minutes after turning off a refrigerator. (If not, oil will leak inside.) 2) Remove retained refrigerant by cutting first high pressure side (drier part) with a nipper and then cut low pressure side. (If the order is not observed, oil leak will happen.) Suction tube

Others.
Condenser
High Pressure side
1) Be sure to replace drier when repairing pipes and injecting refrigerant. 1) Weld under nitrogen atmosphere in order to prevent oxidation inside a pipe. (Nitrogen pressure : 0.1~0.2 kg/cm2.)
1) Nitrogen only should be used when cleaning inside of cycle pipes inside and sealing. 2) Check leakage with an electronic leakage tester. 3) Be sure to use a pipe cutter when cutting pipes. 4) Be careful not the water let intrude into the inside of the cycle.

* When replacing a drier: Weld ①and② parts by blowing nitrogen (0.1~0.2kg/cm2) to high pressure side after assembling a drier. * When replacing a compressor: Weld ③and④ parts by blowing nitrogen to the low pressure side. Note) For other parts, nitrogen blowing is not necessary because it does not produce oxidized scales inside pipe because of its short welding time. ※ KEYPOINTING Welding without nitrogen blowing produces oxidized scales inside a pipe, Which affect on performance and reliability of a product.

※ KEYPOINTING 1) If power is applied during vacuum degassing, vacuum degassing shall be more effective. 2) Operate compressor while charging refrigerant. (It is easier and more certain to do like this.)
4.Refrigerant charging.
* Charging sequence 1) Check the amount of refrigerant supplied to each model after completing vacuum degassing. 2) Evacuate bombe with a vacuum pump. 3) Measure the amount of refrigerant charged. - Measure the weight of an evacuated bombe with an electronic scale. - Charge refrigerant into a bombe and measure the weight. Calculate the weight of refrigerant charged into the bombe by subtracting the weight of an evacuated bombe. Indicate the weight of an evacuated bombe ※ KEYPOINTING 1) Be sure to charge the refrigerant at around 25°C.
Calculation of amount of refrigerant charged the amount of refrigerant charged = a weight after charging - a weight before charging (a weight of an evacuated cylinder)
62
Items 4.Refrigerant charging.
Precautions 4) Refrigerant Charging Charge refrigerant while operating a compressor as shown above. 5) Pinch a charging pipe with a pinch-off plier after completion of charging. 6) Braze the end of a pinched charging pipe with copper brazer and take a gas leakage test on the welded parts.

5. Gas-leakage test
* Take a leakage test on the welded or suspicious area with an electronic leakage tester.
6. Pipe arrangement in each cycle
* Check each pipe is placed in its original place before closing a cover back-M/C after completion of work.
9-4. Standard Regulations for Heavy Repair
1) Observe the safety precautions for gas handling. 2) Use JIG (or wet towel) in order to prevent electric wires from burning during welding. (In order to prevent insulation break and accident.) 3) The inner case shall be melted and insulation material (polyurethane) shall be burnt if not cared during welding inner case parts. 4) The copper pipe shall be oxidized by overheating if not cared during welding. 5) Not allow the aluminum pipes to contact to copper pipes. (In order to prevent corrosion.) 6) Make sure that the inner diameter should not be distorted while cutting a capillary tube. 7) Be sure that a suction pipe and a filling tube should not be substituted each other during welding. ( High efficiency pump.)
